When I test the systems individually all work perfectly and the results are the same in mt5 and in sq x. However, when using them in a demo portfolio they somehow collapse and close the orders all at once, these two systems that I attach work perfectly individually, but when using them together their orders sometimes last 5 minutes sometimes 10 minutes. The systems are 10 and 15 minutes long and their orders last one bar. The magic numbers are obviously different and the EAs were placed in different charts, of course the 10 minutes one went to a 10 minutes chart and the 15 minutes to a 15 minutes chart.
